The attack is called Greatest horn, so it's probably different from the Great horn we're familiar with.

Ah, yeah, that's more like it . Good argument.

But, if we go by its name "Greatest Horn", doesn't it indicate that it's more powerful than Great Horn? So, if Great Horn can obliterate enemies in an instant, how come Greatest Horn only sent enemies flying? That's a question for future episodes, btw . I know that nobody can answer it now since we still don't know the exact technique or how serious Taurus throw his Greatest Horn at our MCs.
